Скачать или смотреть What is 3D image segmentation? Creating a 3D model from scan data for beginners

If you are creating a 3D model from scan images, you might be wondering what is 3D image segmentation? In this video, I will explain the basics behind the process and required software needed to create a 3D model using image segmentation, that is easy to understand for beginners.

3D image segmentation is the process of taking a set of scan data, usually CT or MRI DICOM files, and coloring the region of interest, slice by slice. By the time you make your way through all the images, you have a 3D model. The pixels of each scan are actually not 2D but have a thickness, so they are 3D and are called voxels. But what are voxels? Well, this can be difficult to explain, so I like to use the analogy of bread slices. When you look at the slice from the front it looks 2D. But if you turn it on its side you can see that it has a thickness. This is similar to how your scans are made up of 3D voxels.

The resulting 3D models can be used for 3D printing, CAD development, or finite element analysis meshing.
